Abstract
A power input and output system for continuously variable transmission units of the type in which a nutatable traction body is supported both for rotation on the body axis and for nutational movement in which the body axis travels in a biconical path about a primary transmission axis. Power input and output members of the transmission unit are each linked to the nutatable body by gearing to be in direct torque transmitting relationship only with the nutatable body and so that the nutational component of movement is the result solely of traction surfaces on the body being in rolling frictional engagement against complementing and fixed traction surfaces.
